Stanford scientists use Twitter to make more accurate earthquake maps

Beyond the celebrity life updates and the 140-character fights about pretty much anything under the sun, Twitter can actually be helpful when it comes to things like mapping earthquakes.Twitter and a group of researchers at Stanford teamed up to see how tweets could help create more accurate mappings of earthquakes.
